Comparative Fault in Indiana: How Shared Blame Affects Your Settlement

Being partially at fault for an accident does not automatically end your ability to recover compensation in Indiana. What it does is change how much you can recover. Under Indiana's Comparative Fault Act, your damages are reduced in proportion to the fault assigned to you, and only if your share of fault exceeds 50% is your claim barred entirely.

The outcome of any shared-fault case depends heavily on how fault is investigated, what evidence gets gathered, and whether the determination reflects what actually happened. A few percentage points in either direction can mean a difference of tens of thousands of dollars in your final recovery.

Wilson & Novak's personal injury attorneys handle cases where comparative fault is contested and work to make sure clients aren't assigned more blame than the facts support.

How a Fault Percentage Directly Changes Your Recovery

Indiana's comparative fault system requires a judge or jury to assign each party a percentage of responsibility for the accident. Your compensation is then reduced by your assigned percentage. The stakes become clear through two scenarios on the same set of facts.

You're injured in a crash, and your total damages are $90,000. The other driver is found 80% at fault; you are found 20% at fault. Your $90,000 award is reduced by 20%, leaving you with $72,000.

Now, assume the insurer successfully argues you were 55% at fault. Under IC § 34-51-2-6 , your claim is barred entirely. You recover nothing.

Same injuries. Same accident. A $72,000 difference based solely on which fault percentage is held. That gap is why how fault gets determined matters as much as the underlying claim.

The Difference Between an Adjuster's Fault Opinion and a Legal Verdict

After an accident, the at-fault party's insurance company conducts its own investigation and assigns fault based on its own analysis. That number shapes whatever settlement offer they extend, often before you've had time to gather evidence of your own. An adjuster's fault assessment is a negotiating position, not a legal determination, and it carries no binding authority.

If the case proceeds to trial, a jury reviews the actual evidence and reaches an independent conclusion. Insurance companies know this distinction well, which is why initial fault assignments to claimants tend to run higher than what a jury would likely find. Assigning you 40% fault instead of 20% costs you $18,000 on a $90,000 claim, and many claimants accept the lower offer because they don't realize the number can be challenged.

An attorney who builds a competing factual record and argues it effectively can bring that percentage down, in most cases, without going to trial at all.

Common Situations Where Fault Becomes Contested in Indiana

Comparative fault arguments arise most often in accidents where the sequence of events is unclear or where both drivers had some chance to avoid the collision. Situations where fault is routinely disputed include:

• Intersection collisions. When two vehicles enter from different directions, insurers often argue that both drivers failed to yield or observe the signal. Even when one driver clearly ran a light, the other may be assigned some fault for speed or reaction time.
• Left turn accidents. The turning driver generally bears primary responsibility, but insurers commonly argue that the oncoming driver was speeding or had an opportunity to slow. That argument can shift several percentage points of fault.
• Rear-end collisions. The trailing driver is typically presumed at fault, but insurers may contend the lead driver braked without cause, cut into the lane, or had non-functioning brake lights.
• Multi-vehicle accidents. With three or more vehicles involved, fault gets distributed across multiple parties, making each driver's assigned percentage more open to dispute.

The Evidence That Builds a Fault Determination

Fault percentages aren't estimated. They're assembled from evidence, and the stronger that record, the stronger your position when challenging an unfavorable assignment.

• Police reports document the investigating officer's observations and any citations issued. A citation isn't automatically determinative in a civil case, but it carries real weight in negotiations.
• Physical evidence from the scene: skid marks, vehicle damage patterns, road conditions, and photographs taken immediately after impact, before anything is moved or cleared.
• Witness statements from people who observed the accident and have no financial stake in the outcome.
• Surveillance and dashcam footage that can directly contradict an insurer's version of how the accident unfolded.
• Accident reconstruction analysis from specialists who establish vehicle speeds, points of impact, and driver behavior from physical evidence alone.
• Medical records connecting your injuries to the accident, which also counter claims that your condition was pre-existing.

Indiana's Nonparty Defense: When the Defendant Points Elsewhere

One feature of Indiana's comparative fault system that catches many claimants off guard is the nonparty defense. Under IC § 34-51-2-14 , a defendant can assert that some or all of the fault belongs to a party not named in the lawsuit, including a party who was never identified. Under IC § 34-51-2-15, the burden of proving this defense falls on the defendant.

In a car accident case, a defendant might argue that a third driver who left the scene, a government agency responsible for a road hazard, or a vehicle manufacturer contributed to what happened. If the jury accepts that argument and assigns that absent party a fault percentage, the named defendant's share drops, and what they owe you decreases accordingly.

Your attorney's investigation needs to account for every potential contributor to the accident before the defendant raises this defense. Once a nonparty gets assigned fault by a jury, the compensation you could have recovered from parties who are actually in the case is reduced by whatever percentage is handed to someone who isn't there to dispute it.

How Insurers Use the Comparative Fault Framework as a Settlement Tool

Comparative fault is one of the most frequently used tactics insurance companies deploy to limit what they pay out. Common approaches include:

• Obtaining recorded statements shortly after the accident, before the claimant has an attorney, and using answers to build a higher fault assignment.
• Citing minor traffic violations or driving habits to argue contributory negligence, even when those behaviors had little bearing on how the collision actually happened.
• Arguing that a claimant worsened their injuries by delaying medical treatment or returning to physical activity too soon after the accident.
• Claiming the claimant had an opportunity to take evasive action and failed to do so.

Each approach is designed to push your fault percentage as high as possible. Crossing 51% eliminates the insurer's obligation to pay anything.

Challenging the Fault Number Before Your Case Goes to Court

Most comparative fault disputes resolve before a jury hears them. An attorney can challenge an insurer's fault assignment by presenting an alternative account of the accident backed by evidence, exposing weaknesses in the insurer's own analysis, and demonstrating that the actual facts support a lower percentage for the claimant.

Starting that work early matters. Surveillance footage gets overwritten, witnesses become harder to find, and physical evidence disappears from accident scenes. A complete factual record built from the start gives your attorney the strongest position to negotiate a fault percentage that actually reflects what happened.
